[1] | Rayonier will not issue additional shares upon future exchange or maturity of the Senior Exchangeable Notes due 2015 (the “2015 Notes”) due to offsetting hedges. ASC 260, Earnings Per Share requires the assumed conversion of the 2015 Notes to be included in dilutive shares if the average stock price for the period exceeds the strike price, while the assumed conversion of the hedges is excluded since they are anti-dilutive. The full dilutive effect of the 2015 Notes was included for all periods presented. Rayonier will distribute additional shares upon maturity of the warrants sold in conjunction with the 2015 Notes if the stock price exceeds $28.12 per share. The exchange price on the warrants is lower than periods prior to second quarter 2014 as it has been adjusted to reflect the spin-off of the Performance Fibers business. The warrants were not dilutive for the three months ended March 31, 2015 as the average stock price for the period did not exceed the strike price. For further information, see Note 13 — Debt in the 2014 Form 10-K and Note 15 — Debt of this Form 10-Q.
